Description
[technical field]
The utility model relates to steering wheel technical field, is specifically related to the straight line steering wheel that a kind of worm and gear drives.
[background technology]
Non-self lock steering wheel conventional at present, uses motor to connect gear reduction unit and exports.Due to speed reducing ratio comparatively conference cause decelerator comparatively large, such that weight ratio own is heavier, volume is larger.Because itself cannot self-locking, need keep running always, and affect by extraneous disturbing factor very large, the requirement accurately controlled cannot be reached.Existing self-locking type steering wheel is generally brake self-locking, namely in non-self lock steering wheel, has installed brake control.Inherit non-self lock steering wheel shortcoming.
[utility model content]
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, the straight line steering wheel that a kind of worm and gear reasonable in design, easy to use drives, it has the advantages such as required actuating force is little, assembling is simply compact, lightweight, bearing capacity large, stable drive, noise are very little.
The straight line steering wheel that a kind of worm and gear described in the utility model drives, it comprises straight line steering wheel body, and described straight line steering wheel body comprises a shell, and this shell upper is fixed with worm bearing and bearing, this worm bearing and bearing are provided with worm screw, and this worm screw is connected with motor by shaft coupling; Described worm screw is arranged a worm gear, this worm and wheel engages; Described worm gear is arranged on Worm Bearing and bearing, and this Worm Bearing and bearing are fixed in the middle part of shell; Described worm gear is connected with line slideway; Described line slideway is made up of moving meter and retaining element, and this moving meter is set on retaining element; The moving meter contact portion of described worm gear and line slideway is the gear teeth of worm gear; Described retaining element is fixed on the bottom of shell; Described line slideway is provided with displacement transducer.
After adopting said structure, the utility model beneficial effect is: the straight line steering wheel that a kind of worm and gear described in the utility model drives, it can realize reverse self-locking, namely worm gear can only be driven by worm screw, and worm screw can not be driven by worm gear, the feedback loop be simultaneously made up of parts such as displacement transducers can realize the accurate control to running.This mechanism can the operation of accuracy-control system, and mechanism's self-locking after reaching precalculated position, eliminate the impact of external disturbance, its mode exported is displacement, and it has the advantages such as required actuating force is little, assembling is simply compact, lightweight, bearing capacity large, stable drive, noise are very little.
[accompanying drawing explanation]
Accompanying drawing described herein is used to provide to further understanding of the present utility model, forms a application's part, but does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation;
Description of reference numerals:
1, motor; 2, shaft coupling; 3, worm screw; 4, worm bearing and bearing; 5, worm gear; 6, Worm Bearing and bearing; 7, moving meter; 8, retaining element; 9, displacement transducer; 10, shell.
[embodiment]
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1, the straight line steering wheel that a kind of worm and gear described in this embodiment drives, it comprises straight line steering wheel body, described straight line steering wheel body comprises a shell 10, this shell 10 top is fixed with worm bearing and bearing 4, this worm bearing and bearing 4 are provided with worm screw 3, and this worm screw 3 is connected with motor 1 by shaft coupling 2; Described worm screw 3 is arranged a worm gear 5, this worm screw 3 engages with worm gear 5; Described worm gear 5 is arranged on Worm Bearing and bearing 6, and this Worm Bearing and bearing 6 are fixed in the middle part of shell 10; Described worm gear 5 is connected with line slideway; Described line slideway is made up of moving meter 7 and retaining element 8, and this moving meter 7 is set on retaining element 8; Described worm gear 5 and moving meter 7 contact portion of line slideway are the gear teeth of worm gear 5; Described retaining element 8 is fixed on the bottom of shell 10; Described line slideway is provided with displacement transducer 9.
Operation principle of the present utility model is as follows: motor receives the laggard action of actuating signal and does, and drives to line slideway, by the external output displacement of the moving meter of line slideway by worm gear device.Be arranged on the displacement transducer on line slideway and the Displacement Feedback of moving meter is returned control system, and checked by the position of motor action to moving meter.Due to the self-locking performance of worm and gear itself, after moving meter runs to preposition, system stops, and the state of system can not be subject to external influence.
The said Displacement Feedback of the utility model returns control system, and the staff as the industry all can easily design, therefore is not elaborated in the design.
The straight line steering wheel that a kind of worm and gear described in the utility model drives, it can realize reverse self-locking, namely can only drive worm gear by worm screw, and can not drive worm screw by worm gear, the feedback loop be simultaneously made up of parts such as displacement transducers can realize the accurate control to running.This mechanism can the operation of accuracy-control system, and mechanism's self-locking after reaching precalculated position, eliminate the impact of external disturbance, its mode exported is displacement, and it has the advantages such as required actuating force is little, assembling is simply compact, lightweight, bearing capacity large, stable drive, noise are very little.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
